American Airlines spokesman Casey Norton says the pilot requested to land after maintenance light came on. The plane was traveling from Charlotte, North Carolina, to Milwaukee when it diverted to Dayton's airport.

The airline said earlier reports of a possible tire fire were incorrect.

No injuries were reported. Norton says the Bombardier CRJ900 was carrying 74 passengers and four crew members.

Mechanics were expected to evaluate the plane Monday, but Norton says it appears there was a problem with the indicator.

Norton says the plane was a U.S. Airways Express flight operated by PSA Airlines, a subsidiary of American Airlines.
